FOV in detail description of .pano file

When rendering a large pano to KRO RAW, there's no metadata for PTP, and to find out the FOV of the Pano I have to open it in APG again, but 'unimportant' details like used blender etc. can be seen if i rightclick the pano file and look at the details... Maybe it's possible to add the FOV there, too?

If you are on windows, the shell extension parses the .pano and display these information as tooltips.
You can also open the .pano with a text editor and you'll find something like that :

<Type> 2 </Type>
<ThetaMin> -0.802458 </ThetaMin>
<ThetaMax> 0.802458 </ThetaMax>
<PhiMin> -0.347454 </PhiMin>
<PhiMax> 0.288683 </PhiMax>
<FitMode> 1 </FitMode>

Type -> projection mode
ThetaMin/Max, PhiMin/Max => fov

I attached screenshots of what I can get out of my pano file. Opening it in a texteditor and calculating the FOV is a possibility, but it's not really faster than opening it in APG and just look :-) As you can see theres nothing shown about the FOV on my system, oh just found a bug? In my screenshots it says 'planar projection' but it's spherical?

btw. I'm using APG 2.6b2 on intel Q8200 with 8GB RAM and NVIDIA GTX460

Oups. Sorry. The shell explorer doesn't display the fov. But when opening the .pano with autopano, it does, of course : 77.65° horizontal by 45.88° vertical.
You'll still need to vertical offset which is (phiMax-phiMin)/2. You can calculate this value by opening the editor, and in the status bar, you'll have phiMax and phiMin.

No Problem .-)

I found an easy way, just ad %f to the filename in the renderer, as far as I see it will append the FOV and also the vertical offset.

thanks alot!

Btw., I dehazed the 806 images, now image quality is much better, and for the fun of it I imported the images through the gigapan importer in APG 26b2 and 2.5.2, with (as far as I know) identical settings, and in 2.5.2 I have a RMS of 3.93 and in 2.6b2 its above 10? I also discovered a heavy alignmend error somewhere and a single missrotated ble sky image in 2.6b2?

Yes, 2.6 beta 2 has a lot of issues and this is one of them.
